If you buy that from Classic let me know how it works. It looks like the ones I got from Laysons and it did not catch well and it ended up flowing and deforming.
So you have a good one still? Can you take a photo of it? I just sent out a model to have a prototype of one for my '63. After a bit of testing and any changes I plan to get a few printed in nylon and see if they hold up. If that is a fail then @66vert can CNC machine them out of a nylon block. Keep us posted on if these work for you or not.
